Registration must be done via the Google Form online, which can be found at the following web address: There will be no paper registration forms. If you have any questions or need assistance in registering, please contact CoreCon’s Costume Contest staff or a CoreCon staff member.

  2. All contestants MUST show up for workmanship judging and walk through. If you do not attend both events, you will not be allowed to compete. NO EXCEPTIONS! We need to see your costume up close and how you will be presenting it. Both of these are important to judging.

  3. The CoreCon Costume Contest, including Cosplay, is for costumers presenting themes from Science Fiction, Fantasy, Mythology, Anime, Theater, and other realms of the imagination. Costumes that are meant to accurately represent historical or cultural dress are also encouraged. If you are wearing street clothes, you will be asked to exit the stage. Questions can be directed to CoreCon’s Costume Contest staff. All costumes and presentations must be family friendly. If you think your performance or costume might be interpreted by others as offensive or risqué, we ask you to re-evaluate it. Costumes judged prior to the contest as indecent or inappropriate will be disqualified and WILL NOT be allowed on stage.
    If your performance becomes inappropriate while on stage you WILL be asked to leave by the Contest Director. This includes wardrobe malfunction both intentional or unintentional and dialogue or music that might contain material intentionally offensive to persons of any ethnic, racial, religious, gender or sexual orientation.
    Costumes that abide by state decency codes are acceptable. More information regarding the state of North Dakota’s decency codes can be found by using this website link: This rule is meant to encompass all material, including jokes that mock people that are of “alternative” religious groups, sexual groups or differing race or ethnic groups. Do not include swear words (blasphemous, crude or sexual in nature) during any part of your performance. This also includes promoting or making fun of child molestation or child pornography, cruelty to animals, and sexual assault. Additionally, depiction of drug use or underage drinking is frowned upon.
    The Contest Director makes all final decisions and does not need to give any explanation. If you have any questions as to the suitability of your costume or performance, it is in your best interest to contact CoreCon’s Costume Contest staff prior to the close of registration at 5 PM, May 24th, 2024.
    You may register as an individual or group. A person registering as an individual MAY NOT also participate in a group. Entrants may be on stage only once. A group may consist of up to six (6) individuals. A group will be considered a single entity and will only receive ONE prize per category. It is the responsibility of the members of the group to decide how to share it. Any group over six (6) persons needs to first be approved by the Contest Director before the close of registration at 5 PM, May 24th, 2024.

  4. Costumers that win a major award (i.e.; Best of…) at CoreCon are not permitted to compete in that same costume in future years. The person wearing the winning costume is able to compete as long as they wear a new or different costume.

    Is there a fee to register?

      Your convention badge is all you need. There is not a separate fee for the Costume Contest.

    2. Addison Swenson

      Can any age join?

  2. Honey

    If an individual would like to preform a dance do you think the 30 seconds is enough or should they find a new idea?

    1. Soul Consul

      Hi, Honey! It entirely depends on the dance! I’d recommend practicing at home to see if the time limit allows you enough freedom to do what you’d like to do!

    Do you have to have a totally hand made costume?
